Hing W Weston , MA May 07, 2016 Appliance: Thermador RDSS30 S/N 9707 & UP Burner not working REMOVE THE TOP COVER OF THE STOVE. THE VENTURI NUTS WERE FROZEN.WITH THE JET HOLDER I HAVE TO CUT OR DRILL OUT THE VENTURI NUTS TO RELEASE THE STOVE COVER. IN DOING SO THE JET HOLDERS WERE ROTATED RELATIVE TO THE MOUNTING BRACKET, AS A RESULT, THE TWO TUBING ASSEMBLIES WERE BROKEN. I ONLY FOUND ONE TUBING ASSEMBLY ON LINE. THE OTHER ONE I HAVE TO ABRICATE WITH 1/4" COPPER TUBING, COMPRESSION COLLARS AND WITH THE TWO NUTS SALVAGED FROM THE BROKEN PARTS 8 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
